In Object Changeability (Within RSA1 Transport Connection) the Broadcaster entry has been set to changeable for several months - it has helped in that we progress past one error message but the message below about the namespace /bic/ still appears.

Message "Namespace '/BIC/' must be set to 'changeable' (transaction SE06)"

"Notification Number R7 063"

There is an OSS note on this message 797551 but it appears to relate to old releases.
